All of those additional pixels require additional battery and CPU power to drive. By contrast, black-levels, backlight-uniformity, color accuracy, and pixel fill can be improved without trade-offs. Most laptops have a lot of room for improvement in these areas, and IMO they lead to a better picture overall versus increasing the resolution. As a bonus, you also get to side-step a ton of unfortunate software weirdness.
And while adding HDR and increasing the refresh rate does come with battery/CPU/software trade-offs, I still think they're more worthwhile upgrades than merely jacking up the resolution on a small screen.
I have no idea whether the Pangolin screens are terrible on these metrics too, I'd just like to see a lot less focus on resolution. It's actually really hard (impossible?) to find an HDR panel that isn't 4K, and IMO that's a shame. We live in a world where Samsung phones run below their native screen resolution by default in order to conserve battery[1], which makes no sense whatsoever. If the native resolution of the screen was lower to begin with, battery life would be even better, and visuals would be improved overall due to lack of scaling!
